SECONDARY RACK Filed Dec'. 5, 192s Patented June 3, 1930 UNITEn srares NORRS C. H'USTED, OFNILES, OHIO y SECONDARYY RACK i Application led ADecember 3, 1923. ,Serial No. 678,123(A This invention relates to insulator supports and more particularly to that type of support known as a secondary rack.

An object of this invention is to produce a relatively light yet sturdy secondary rack in which the support `arms have well rounded Vtops allowing insulated wire to be pulled in over them without injuring the insulation.

This as well as other objects which will readily appear to those skilled in this particular art I attain by means of the device described in the specication and illustrated in the accompanying drawing.

Figure 1 is a view partially in side elevation and partially in section of a rack embodying this invention. Fig. 2 is a view partially in front elevation and partially in section of the rack shown in Fig. 1 with the insulators and the insulator rod removed. Fig. 3.

is a view taken on 'the line 3`3 of Fig. 1 looking in the direction of the arrows and Fig. l is a top plan view of a blank from which the support arms of the rack are pressed. v v

The rack constructed in accordance with this inventionconsists of a base made up of two rolled angle sections arranged in reverse, parallel and spaced relation so that the legs 5 and 6 of the sections lie in the same plane 3o and the legs 7 and 8 project outwardly and forwardly from the legs 5 and 6 to form a channel 9 which extends longitudinally of the base.

Support arms formed from blanks preferably shaped as shown in Fig. 4; are formed up so as to resemble, in cross section, an inverted U. The ears 10 and 11 of the blanks are bent at a radius and at an angle to the body portions 12-12 to form well rounded tops to the arms. lVhen the waist portion 13 is bent so that the body portions 12-12 stand parallel one with the other the ears 10 and 11 lie adjacent one to the other and a longitu dinal channel 14; is provided which extends from the insulator rod opening 15 to the legs 7 and 8 of the angle sections.

The feet 16 of the arms are pierced as shown at 17 to receive the rivets for securing the parts together. The ends of the feet rest 5 against the outer faces oflegs 5 and 6 and` straddle the legs 7 and 8. Longitudinally split tubular spacers 18 are positionedrbe-` tweenlegs 7 and 8 and a single rivet 19 se-A curing each arm infplace and passes through holes 17 in the feet of the arm, holes in the legs 7 and 8 of the angle sectionandvthrough the spacers 18.

Legs and 6 yof the base areprovided with elongated slots 20 for fastening the rack to luildings where through-bolts cannot be user.

Having thus described by inventionV what Iclaim is: Y

1. ln a secondary rack, two angle sections arranged in reverse and parallelrelation to 'i ferm a rack base havinga flat back and forwardly projecting legs, longitudinally split support arms extending outwardly from t-he base and arranged so that their inner ends straddle said forwardly projecting legs so as to bear against the legs of the sections standing at an angle to the forwardly projecting legs and securing means extending through the endsjof said arms and through the outstanding legs of said sections. j

2. In a secondary rack, two angle sections Zin' arranged in reverse, parallel and spaced .relation to form a rack base having a flat back vand a longitudinal channel flanked on opposite sides by the adjacent forwardly projecting legs of said sections, longitudinally split support arms extending outwardly from the base and arranged so that their inner ends straddle said forwardly projecting legsY so as to bear against the legs of the sections Standing at an angle -to the forwardly projecting legs, spacers positioned between Y said forwardly projecting legs and securing means extending through said spacers, through the ends of said arms and through the outstand- Y ing legs of said sections. v

3. In a secondary rack, two angle sections arranged in reverse, parallel and spaced relation to form a rack base having a fiat back and a longitudinal channel flanked onopposite sides by the adjacent forwardly projecting legs of said sections, longitudinally split support arms extending outwardly from the base and Varranged so that their inner ends Y straddle said forwardly projecting legs so as to bear against the legs of the sections standing at an angle to the forwardly projecting legs, tubular longitudinally split spacers positioned between said forwardly projecting legs and securing means extending through said spacers, through the ends of said arms and through the outstanding legs of said sections.

4. In a secondary rack, two angle sections arranged in reverse, parallel and spaced relation to form a rack base having a fiat back and a longitudinal channel flanked on opposite sides by the adjacent forwardly projecting legs of said sections, U-shaped support arms extending outwardly from the base and arranged so that their inner ends straddle said forwardly projecting legs so as to bear against the legs of the sections eX- tending at an angle to the forwardly projecting legs, securing means extending through the ends of said arms and the forwardly projecting legs of the sections and means for mounting insulators between the outer ends of said U-shaped support arms.

5. In a secondary rack, two angle sections arranged in reverse, parallel and spaced relation to form a rack base having a flat back and a longitudinal channel flanked on opposite. sides by the adjacent forwardly projecting legs of said sections, supportarrns eX- tend-ing outwardly from the base and arranged so that their inner ends straddle said forwardly projecting legs so as to bear against the legs of the sections extending at an angle to the forwardly projecting legs, securing means extending through the ends of said arms and the forwardly projecting legs of the sections and means for mounting insulators between the outer ends of said support arms.

In testimony whereof, I have hereunto subscribed my name this 23 day of October, 1923.
